Chapter 1
A dimension between dimensions. Where all the universe could be seen. Within, was the multiverse's most powerful entity...Steven Universe. He had spent many years training and increasing his power. It had finally reached godly levels, and he knew this was a good a time as any to finally make his move. He looked at all the universes that knew his name. Everywhere he had tried to invade using a mirage of himself and failed. But with his powers, he could now do what he was planning all along. Using his powers, he took the viewports to all the universes, and started bringing them together. Soon, they all suddenly converged into a single universe, creating a mega-verse with all those he had encountered over the years.
Steven: The Convergence has begun...
At the Beach City beach house, the Crystal Gems were in disarray. They knew Steven would be coming, but they didn't know when. They suddenly felt a massive tremor, knocking them off balance.
Amethyst: Woah, momma.
Pearl: What's happening?
Garnet: I don't know.
The tremors soon subsided.
Pearl: That was unusual.
Amethyst: Think it was just an earthquake?
Garnet: Right. A massive earthquake on a location thousands of miles from the nearest faultline, that hasn't had a single earthquake for the thousands of years we've been here? Something else is up. Gaaah!
Garnet grasped her head in pain.
Amethyst: Garnet? What's wrong?
Garnet: I just felt a rip in the fabric of space-time. A portal was opened somewhere.
Pearl: Oh no. He's free.
Amethyst: We are dead! We are so dead!
Garnet: Now, hold on. We all knew this day would come, sooner or later. I guess it's sooner.
Pearl: What do we do? We can't fight him if he's at full power.
Garnet: Pearl! It's ok. For all we know, he's on the other edge of the universe. It could take him centuries, or millennia to get...he's here.
A dark meteor crashed in front of them, and Steven rose form the crater. He was glowing dark purple with black highlights, and he had glowing red eyes. He had multiple necrotic bladed appendages emerging from his back as regal accessories. His voice was lower, calmer, which made it seem almost twice as menacing.
Steven: I'm back.
Amethyst: Uh. H-Hey Steven! I-I-I-It's g-g-g-great to see you again. In real life, and not just in my nightmares.
Steven: Funny.
Amethyst was thrown into the wall by an unseen force.
Steven: Never made the cut for anyone's nightmares.
Garnet and Pearl drew their weapons. Garnet brought her fist down on his head, and successfully made contact. Steven was completely unfazed by the attack. He touched Garnet's chest, and she was thrown next Amethyst. Steven turned his attention to Pearl, who attacked him multiple times with her spear, and he blocked every attack with only his finger. He grabbed the spear, bringing it down to the ground, and flicked Pearl in the head, sending her to the others.
Steven: I think I'm done here now.
Amethyst: Why would you come all the way out here just to fight us then leave?
Steven: To show you just what it is you're up against. To show you what will happen if you try and stop me. I will tear down everything you care about or fought to protect, and make your worst nightmares come true. And the tremors you just felt? All the universes I've been in have converged into a mega-verse. It will really spark the reader's interest by having everyone in one story.
Amethyst: What are you talking about?
Steven: That's right. You don't know. Ah, well. You will know soon enough. Have a nice day.
Steven disappeared as he rocketed into the sky.
Pearl: That was...
Amethyst: Ridiculous. I mean, I knew he'd be strong, but not that strong.
Garnet: This is going to be harder than we thought. We're gonna need help. If Steven did combine the different universes together, we can get help from all the universes we've visited.
Pearl: Then we'll split up to find them all.
Amethyst: Let's do this.
